Myinvention relates to devices for burning garbage and the like wherein Ythere are superposed compartments, the lower oneV of Y which serves to heat and dry the garbage which is preliminarily placed inthe upper compartment and thereafter transferred to the lower compartment for nalcombustion.

' to provide an improved The principal objects of myl invention are Y device. of this charf acter having ay combustion chamber and a 'dryingeompartmena in the latter of which garbage `is exposed to and dried bythe heat from the combustion chamber and then conlveniently transferred to and used as fuel inI the combustion chamber; tofconstruct the drying compartment so thatit may func-V tion as `a combustion chamber ,to provide .a draft outlet which permits'circulation'.v ofir airfthrough the drying compartment as well as the combustion chamber; toV regulate the communication of each4 compartment withy the draft outlet or stack; to control the cir culation of Vheated gases from the combustion chamberfthrough the drying chamber; to

prevent escape of odor from the garbage in the incinerator ;and in general to provide a simple, convenient and Y drying and burning garbage andthe like. 0n the drawingz y Fig. 1 isa front view of the incinerator with a ortion at onesidebroken away toV show a fragmentaryfysection on" the linel-l of Fig. 2,

Referring tothe drawing, 'the reference numeral 1 indicates the casing which maybe of any suitable construction, preferably rec- `*,tangularin horizontal section, said casing being closed by a bottom wall 2 and supportlpart of the casing, Vand rearf'walls .8 and 9 respectively, which eective device for I ed by the feet Theupper end of the casing 1 isclosed byV a cover: pla-te -4 which is secured to the-casing4 and has an inclined frontwith a large opening 5 closed by a door 6, hinged tothe 'cover plate 4 as at 7 The door 6 'affords access to the drying compartment whichis located in the u per and has the inclined ront lextend between the side walls of the casing and incline downwardly to grate 10 which is supported in guides 11, which are secured ,tothe side walls vof the casing 1, and said grate 10 may be shifted back and forth in said guides to shake the'grate orA dump the contents of the. drying compartmentinto the combustion chamber. For operating Vthe grate 10, the-,latter has a stem 12fadjacent each end and long enough so that when-the grate'is in the normal position closing thev bottom of the drying compartment, 'said'v stems project through apertures 13. provided j therefor in the front wall'of the casing 1, and a bail14 Vhas theends ofits arms pivoted to the outer extremities of the Vstems 12 s o` that it may be dropped down to a position wherein the arms of the bail are in line'with thestems 12. When in this 'position the bail lmay be operated to slide the grate 10 rearf. "f

wardly in the guides `11 and openthe bottom of the drying compartment so as to dump the contents of the drying compartment intol theV combustion Vchamber therebelow,v and when the grate 10 is again'drawn forwardly by means of the bail 14, the latter may be swung upwardly and held in the upraised position by engagementwith a latch 115.4

'The Vguides 11 also servefto support fire brick 16 which formthe side -walls of the dry-,QV 'i ing compartment, the said guides being pro-` vided" for this vpurpose with a `topledgel 1,7

.having upstanding ears 18 along the inner edge and spaced from the respective side wall ofthe casingtohold the lower edges of the tile or firebrickl therebetween.L

These guidesll may be supported in any convenient manner as for eXampleby bolts 19 engaging through the side walls of the casingfand vthe guides, andthe latter may have recesses 20 at intervals therealong to ner that the grate 10 is operated.` Y Y For affording access tolthe combustion l contains an ash pan 30, is accessiblethrough i `trolled by a damper33 'for regulating the draft. 1

' the; wall 22 andthe grate receive theI4 nuts of the bolts 19 and avoid supported in guides 24. lThe guides 24 may a be constructed and mounted in the same manner as the guides 11 and support fire .brick 25 which form the'side walls of the combustion chamber. The grate 23 may be operated in any desired manner, as by the bail 26, which isconnected to stems4v 27 on the grate 23 andl may be released from a latch 28 and dropped down to a horizontal position to shake or shift the grate 23 in the same. man.-

chamber the front wall ofthe'v casing 1 is provided with an opening at the upper end of the combustion chamberwall 21, closed by a door 29, and the space below the grate 23 which an opening. in the front of the casing closed by a door 31 and through which the ash pan may beinserted and removed.- This door 31 isl also provided with draft openings 32 con'- For` enforcing combustion of thecontents ofthe, combustion chamberva gas burner 34 is arranged .along the lower edge of the wall v 22 with orifices 35 at the front discharging through vaspace between the lower edge of 23, said burner having the usual air lmixing or intakefconstruction at theouter endasindicated at 36 i and being provided with a valvev 37 for reguc 38 for a -pipe connection, and ltheback wallv 9 of thev dryingcompartment extends up' the draft'outlet from these chambers,a damper 40 ispivoted at the rear edge of the ledgetion chamber,

latingthe supply of gas to the burner.

The rear wall of the casing 1 near .the top has a smokesl outlet surrounded Yby a flange wardly approximately to the .centerof the smoke outlet, and has a ledge y39 extending diametrically across the smoke outlet so thatV the upper portion of the latter communicates Ywith A`the drying compartment, and the lower'portion of the outlet communicates with the combustion chamber and thusaifords a draft outlet from. each. `For regulating 39 sothat it may be swung upwardly to regulate yor close the outlet from the drying compartment, or swung downwardly to regulate or close the outlet'from'the combussaid damper having a handle l41 at the side of the casing which may be arranged to counterbal'ance the weight of the damper 40 Y and maintain the latter in anyV position to which it may be adjusted. A deiector plate 42 is also preferably provided on the cover 4 and extending across from side to side of the drying chamber substantially as shown in Fig. 2.

For convenient operation vof the door 6 through whichV garbage is deposited in the drying chamber, said doorkfis providedfat one end with an integral arm 43 extending beyond theside of the casing 1 and connectedby a link 44 with the'rear end of the pedal bar 45 which is pivotedat 46 on the base of the casing and provided with a tread portion 47 at the forward end whereby pressure of the foot on said portion 47 will rock the pedal bar 45 and through its connection with. the door 6 raise the latter to the .open position.-

' In the operation of this incinerator a fire' is started in vthe combustion chamber. :Gar' bage may be used for this purpose if desired, and the burner Y Y combustion thereof. Garbage is `then*v del' 34 ignited kto dry and enforce posited inthe'drying chamber andsubiected to the heat froml the 'combustion chamber at which time the Vdamper 40 may beadjusted,

'as req{uired,"to enforce circulationthrough :j'

the dryingV chamberfor facilitating thedry-j ing and to carry way any odorsgivengofl' as the garbage is being heated 4 anddried.

When the garbage inthe drying chamber-is sufficiently dried thefba'il 14 is released from 1I the catch- 15 which -holds'rit inthe normal" ,upraised position, and is dropped down toy thev horizontal position `and pushed rearwardly so as tov slide the -'grate 10 rearwardly in( the guides `11 and allow the' dried garbage inthe drying chamber 'to drop down into 'the com! bustion chamber where it serves` asi fuel to' maintain `'a iirein the Vcombustion chamber' and `dry any further garbage that is deposited" in the-drying chamber.V f'
